The invention relates to a three-satellite cooperative tethered racemization dragging method and system for a space rolling object. The method comprises the steps that a three-satellite cooperative racemization space configuration is established; the structure is composed of three service satellites with maneuvering capability, the first service satellite and the second service satellite are symmetrically distributed relative to the mass center of the rolling object, the distances between the first service satellite and the mass center of the rolling object and between the second service satellite and the mass center of the rolling object are equal, and the third service satellite is distributed in a spinning plane passing through the mass center of the rolling object; and according to a racemization strategy of firstly eliminating a nutation angle and then eliminating a spin angular velocity, on the premise of ensuring the attitude stability of the rolling object, the tasks of racemization and dragging deorbit of the rolling object are completed. Compared with other existing contact type racemization schemes, the risk of accidental collision is reduced; the racemization strategy in the method solves the problem that the racemization effect of a tether and a rope net on a rolling object is limited; compared with non-contact racemization, the tether can provide large pulling force, racemization time is shortened, and follow-up dragging operation can be carried out.

    本申请涉及一种三星协同对空间翻滚物体绳系消旋拖曳方法与系统,该方法包括:建立三星协同消旋空间构型;该构型由三个具有机动能力的服务卫星组成,第一服务卫星和第二服务卫星相对于翻滚物体的质心对称分布,第一和第二服务卫星到翻滚物体的质心的距离相等,第三服务卫星分布在过翻滚物体的质心的自旋平面内;根据先消除章动角再消除自旋角速度的消旋策略,在保证翻滚物体姿态稳定的前提下,完成对翻滚物体的消旋以及拖曳离轨任务。相比于现有的其它接触式消旋方案,减小了意外碰撞的风险;本方法中的消旋策略解决了系绳及绳网对翻滚物体消旋效果有限的问题;相比于非接触式消旋,系绳可提供较大拉力,减小消旋时间,且能进行后续的拖曳操作。
